The DAP Audio PR-32 40W is a compact speaker designed for various audio applications, offering a balance of power, impedance, and frequency response within a durable enclosure. This manual provides essential information for safe operation, installation, and maintenance of the device.
Function Description
The PR-32 40W is a loudspeaker unit, part of the DAP Audio range, intended for sound reproduction. It is designed to be connected to a power amplifier and a mixer to form a complete audio system. Its primary function is to convert electrical audio signals into audible sound, suitable for various indoor environments. The speaker is built to deliver clear and consistent audio output, making it a versatile component in small to medium-sized sound setups. It can be mounted using a clamp or placed on a flat surface, offering flexibility in deployment.
Important Technical Specifications
The PR-32 40W boasts several key technical specifications that define its performance and compatibility:
- Power Consumption: 40W RMS. This indicates the continuous power handling capability of the speaker, ensuring it can operate reliably at this power level.
- Impedance: 16 Ω. This high impedance value makes the PR-32 suitable for connection in parallel with multiple speakers to a single amplifier channel, allowing for more speakers to be driven without overloading the amplifier.
- Woofer: 3.5". The woofer is responsible for reproducing lower and mid-range frequencies, providing a solid foundation for the sound.
- Tweeter: 12.6 mm Mylar Dome Tweeter. The Mylar dome tweeter handles the high frequencies, contributing to crisp and detailed audio reproduction.
- Frequency Range (-10 dB): 65 Hz - 20 kHz. This wide frequency response ensures that the speaker can reproduce a broad spectrum of sounds, from relatively deep bass to clear highs, making it suitable for music and speech.
- Connections: Speaker cable connector IN. This standard connection type allows for easy integration into existing audio systems.
- Color: Black. A neutral color that blends well into most environments.
- IP Rating: IP20. This rating indicates that the device is protected against solid objects larger than 12.5 mm but has no protection against water. Therefore, it is strictly intended for indoor use and must be kept away from rain and moisture.
- Dimensions (LxWxH): 153 x 160 x 215 mm. These compact dimensions make the speaker easy to place and transport.
- Weight: 3.2 kg. A relatively light weight for its size, contributing to ease of installation and portability.
Usage Features
The PR-32 40W is designed for straightforward setup and operation, but adherence to safety guidelines is crucial:
- Installation Flexibility: The speaker can be mounted to any kind of truss with a clamp or simply placed on a flat stage floor, offering adaptability for different event setups.
- System Integration: The manual illustrates a typical setup involving a mixer (e.g., GIG-104C) and a power amplifier (e.g., P-400), demonstrating how multiple PR-32 speakers can be connected in parallel to the amplifier. This configuration allows for scalable audio solutions.
- Power Matching: It is critical to ensure that the power supply voltage matches the product specification (e.g., do not operate a 120V product on 230V power).
- Cable Management: Users are advised to use cables of the right gauge, especially for long runs, and to maintain clear color indication and polarity throughout the system to prevent damage and ensure optimal sound quality.
- Input Level Management: Avoid setting the input signal level higher than required to drive the equipment to full output, as extreme frequency boosts with high input levels can overdrive the equipment.
- Environmental Considerations: The device is for indoor use only. It must be kept away from water, other liquids, flames, and flammable liquids or gases. Sudden temperature fluctuations should also be avoided, as condensation can damage the system.
- Sound Adjustment: If the sound is warped or distorted, users may need to adjust treble or bass levels. The manual suggests that rooms with few furnishings might require reduced treble, while speakers too close to a wall might require reduced bass to prevent unwanted reflections and "tinny" or boomy sound.
- Troubleshooting Guidance: The manual provides a troubleshooting section for common issues like "No Sound" and "Sound Warping," guiding users through checks for cable connections, power supply, and speaker condition before recommending professional servicing.
Maintenance Features
The PR-32 40W requires minimal maintenance, focusing primarily on cleanliness and proper handling:
- Cleaning: The unit should be kept clean by wiping the cover with a damp cloth. It is important to disconnect the mains power supply before cleaning. Alcohol or solvents should not be used.
- Connection Care: Audio connections should be kept clean. Disconnect electric power, wipe connections with a damp cloth, and ensure they are thoroughly dry before reconnecting equipment or supplying power.
- No User-Serviceable Parts: The device contains no user-serviceable parts. All servicing, repairs, and electrical connections must be carried out by qualified technicians to avoid voiding the warranty or causing further damage.
- Handling Precautions: The manual emphasizes not opening or modifying the device, not removing warning labels, and ensuring cables are not left lying around to prevent accidents.
- Shipping and Returns: In case of return, the product must be sent prepaid in its original packing with a Return Authorization Number (RMA). Proper packing is essential to prevent shipping damage, which is the customer's responsibility. Claims for shipping damage must be reported immediately upon receipt.
By following these guidelines, users can ensure the safe, efficient, and long-lasting operation of their DAP Audio PR-32 40W speaker.
